Sampling for Sulphuric Acid Mist

Tomorrow I’m travelling over to Leeds to attend a seminar organised by the Chemical Industries Association seminar  on Controlling and Measuring Occupational Exposure to sulphuric acid mist. I’ll be making a brief presentation on sampling methodologies. I’ve uploaded a copy of the presentation to my Slideshare site, and it can be viewed below. Exposure toContinue reading “Sampling for Sulphuric Acid Mist”

Some implications of exposure variability

In our last post we saw how inhalation exposures to hazardous in the workplace are highly variable. The spread of results from an air sampling survey is usually quite wide and will usually conform to a skewed log-normal distribution. This means that although there is a large spread of results the majority of exposures areContinue reading “Some implications of exposure variability”

Variability in exposure measurements

Whenever an occupational hygienist carries out an air sampling survey, either for a group of workers carrying out the same tasks in a similar way, or for the same individual worker carrying out the same job on different days, it’s inevitable that a range of results will be obtained.  However, although most people would probablyContinue reading “Variability in exposure measurements”

Measuring hazardous substances

To me, the main aim of occupational hygiene is controlling exposure to hazardous agents, including hazardous substances, to do that its important to understand the degree of risk. That’s the only way we can ensure we’re directing our effort, energy and money at the real problems. With hazardous substances, measurement of their airborne concentration isContinue reading “Measuring hazardous substances”
